5. (10 points) I encrypted the lyrics of the song My Love by the band Westlife (one of my favorite songs back in Middle-School), using the applet for mono-alphabetic substitution from our class website. Here are the letter frequencies for the ciphertext ciphertext: ABC DEFG HIJKL M frequency: 12 0 25 50 24 61 130 16 770 84 79 0 51680 101 33 64 214 30 3251925104 As a love song, we know that the plain-text contains the word "love" and this word has been encrypted somewhere within the ciphertext. We have two candidates for the cipher image, "ODNL" and "SGCT". Use the Chi-square test to determine which is more likely. Use the following table to obtain (theoretical) probabilities of plaintext English letters: letter:rodhf frequency: 130 93 78 77 74 74 73 63 44 35 35 30 28 27272519 16 16 13 953 3 21 5.
